Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 to Fig. 8 is refer to, big key anti-deformation is switched mainly by panel（Not shown in figure）, button 11, pressing plate 12,
Inner seat 13, copper piece combination 14, middle plate fixed mount 15 form.Pressing plate, inner seat and copper piece combination are installed in middle plate fixed mount, are pressed
Plate is located at copper piece combination above, and inner seat is arranged on pressing plate, and button is located above inner seat and pressing plate, and panel is arranged on above pressing plate
And positioned at button periphery, designed by the mutual cooperation between all parts（Including following each improvements）, form greatly by
The overall system architecture for preventing deformation of key anti-deformation switch.
As shown in Fig. 2 pressing plate employs T-shaped location structure 4, pressing plate is formed by T-shaped location structure and copper piece combination 14
Interactive positioning, ensure that copper piece combination 14 and middle plate fixed mount 15 tightly coordinate, such interactive structure can form one can be with
The space of deformation, even if switch overall deformation, copper piece combination 14 also can be within design variations degree, and allomeric function will not change.
Combined by setting some T-shaped muscle positions to position copper piece, in the position of fixed copper piece combination using T-shaped staggeredly, guiding can be limited
Copper piece combines displacement so that when entirety changes, the position of copper piece combination displacement can be controlled in appointed place.
Pressing plate, middle plate fixed mount are positioned with withdrawing pattern face, and pressing plate is adopted using groove positioning from bottom to top in mold design
With the T-shaped muscle position positioned with middle plate fixed mount draw taper in the same direction so that overall positioning can be controlled in superfine scope,
So that the close-fitting performance of pressing plate and middle plate fixed mount is more excellent.
As shown in figure 3, inner seat 13 employs trapezoidal spring positioning pit 5, trapezoidal interior hole（Trapezoidal spring positioning pit）Ensure
Spring bending direction wherein is fixed, and deformation space is sufficient, is to ensure switch（Big key anti-deformation switchs）In special case
Under remain to the stable key used.Spring positioning pit is set to trapezoidal, is moved with the draught control spring of minimum in assigned direction, is
Overall deformation provides the surplus of abundance.
As shown in figure 4, middle plate fixed mount 15 employs overall bow-shaped structural 3 so that it can be carried out in the range of design
Deformation, ensure switch installation Deformation control in scope of design.Middle plate fixed mount entirety arch provides suitable deflection, protects
Intensity is demonstrate,proved.Prevent deformation design from providing the foundation for what is entirely switched so that when switch deforms in scope of design, Ge Geling
Part can be on accurate position.
As shown in figure 5, using simple counnter attack mechanism, it is provided with the inwall of middle plate fixed mount bow-shaped structural horizontal plane
Counnter attack post 8, without other unnecessary structures, hole and support are lacked, have strengthened middle plate fixed mount internal intensity so that control is opened
Overall elastic deformation is closed to be possibly realized.Increase the structure of counnter attack at pressing plate and middle plate fixed mount positioning, succinct fool proof, save
Materials and space, reduce unnecessary cooperation, it is overall more stable.
As shown in fig. 6, structure of the big key anti-deformation switch using the positioning of line face, button 11 are provided with perpendicular to panel
Small wall thickness 2（In left and right two side inner walls of button）, middle plate fixed mount 15 is provided with the small muscle position 1 of band fillet, each side of button
Be respectively provided with a small wall thickness close to two end portions on the inwall of face, the small muscle position of band fillet be arranged on middle plate fixed mount with it is small on button
Wall thickness is corresponding or the position that is engaged.Arrangement above so that button and middle plate fixed mount contact area are small, small apart from gap.
The utility model is using parallel line surface contact positioning, button and the parallel line that the located lateral of middle plate fixed mount is no gradient
With the positioning in face, contact area is small, and positioning precision is high.Such positioning materials are few, good control simple for structure, even if switch is overall
It is distorted, the line and face that two parts position do not have differential seat angle, it is ensured that overall gap is stable.
As shown in fig. 6, being provided with swing piece guide structure 16 with swinging piece correspondence position on middle plate fixed mount, middle plate is fixed
Frame swings piece guide structure and guided piece is swung all the time on the position of design, and ensures that swing piece position is accurate.Swing piece guiding
It is some right that structure includes（It is preferred that four pairs）The small guide post being located along the same line, each pair guide post opposite face top are set to V-arrangement
Structure.On middle plate fixed mount contact chip parallel support structure 17, contact chip parallel support structure are provided with contact chip correspondence position
Including four the support column with vertical notch, four support columns form a rectangles, and four support columns are located at rectangle respectively
Four angles on, respectively there are two support columns on the both sides of small guide post, and the notch of support column both faces towards small guide post.Arrangement above,
So that interior angle drift condition will not occur for product component.Copper piece integrated positioning is interacted, positioning is interacted before and after contact chip, protects
Demonstrate,prove silver point and switch overall close-fitting.Springboard guiding installation, springboard installation dislocation is prevented, guides it to and reaches finer sprocket bit
Put.Parallel support silver point, silver point are supported using parallel double muscle positions, and silver point remains relatively parallel.
Designed as shown in fig. 7, button is fixed using two-way isolating construction（Vertical direction is located separately up and down）So that deformation
Shi Buhui produces multi interference, and button is provided with special support button bit, and the perpendicular positioning and horizontal location of button are only by two respectively
Vertical button bit is in charge of.Vertical downward direction control is controlled using without support button bit 6 vertically upward on without button support 7.Greatly
Button anti-deformation switch key by the small wall thickness perpendicular to panel, vertical downward direction control without buckle support, vertically upward
Using without button bit is supported, realizing, positioning vertical direction is located separately up and down, horizontal direction small―gap suture positions.
As shown in figure 8, big key anti-deformation switch uses self-locking through the fixed contact piece 9 of position 10.
Pressing plate, copper piece combination, middle plate fixed mount of the utility model big key anti-deformation switch more than after improvement, with
And ensure that switching function part relative position is indeformable through position fixed contact piece, contact chip parallel support structure etc. using self-locking.
Cross section provides rational elastic deformation for the middle plate fixed mount of arch for switch, and middle plate fixed mount and the mutual of copper piece combination are determined
Bit architecture, ensure that switching function component relative position is stable, plus other a series of auxiliary location structures so that switch can be
Still safe and reliable use during in face of severe installation environment.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it is all contained within the scope of protection of the utility model.
